'lliese jets or nipples are of a predetermined length and situa-ted far enough apart in pairs to cause thel streams of` ga's and air issuing therefrom -to'impinge and come into confluence a. substantial distance above the wall and' ring when the flow of gas and pressure are suilicient to bring about a meeting of the streams. Otherwise a separate llame .blue green in color is maintained at the mouth of each Vjet and thepresent burner functions so4 well that the gas nia)1 be cut oil' nearly 4in its entirety, or the gas pressure reduced to .the burner to- 1/50 of an incli water pressure and still permit a small i bead of blue flame to exist` at the mouth ot cach jet. Vhen'turncdA en, the converging .streams of gas and air will 4produce a coluinn of green orblue-o ange flame of substantial height centrally between cach pair ot converging jets. 'llie burning of tliegas, either high or low, is protected by annular skirt 8 and the otherwalls of the unit, and the central part of wall 7 lies in a lower plane than-the top of ring 14 and serves as a protecting diaphragm and -also as a drip pan centrally' within the burner. A small eircular air intake opening (l is provided ai the center lof the diaphragm and gas-dn:-

-tributing rino', and 'other 'openings 4 ni'ay also be providiidopposite bosses 1:"2- to admit a restricted mount' 'it air to the group oi' jets and vthe eiitral part of the lieatci'. 'l`lie border edge 19 of opening (i and anv'otier air opening -wliich nia): be used, is beaded or flanged upwardlyv more or less' to provide a shallow water collecting and maporating;l space within-higher ringr ll. An intake pipe -or extension l is east integri-al with -thc gas ring and top wall and this intake may extend laterali) through sliiit S as sliown-in Fig. 1, or it ina v he projected above the top of wall 7 as shown in Figs. 6 and 7, ard pass through .suitable openings formed in the meeting edges oflhe .stationary and hinged body sections of' the lieat'er.

Any suitable gas valve and gas cont rolling or re ulating device may be used lor the u nit, ut as such devices forni no part of BEST AVAiLAeL com' this invention none are shown herein:- However in some instances it is desirable'to have agas intake pipe connect with the base-'unit without passing throughan opening inthe body or shell, and in Fig. .1,-I show the hollow gas ring as depressed and lying below the-tcp of Athe unit- Ito permit the sta tional-y part 2 of the body' or shell to be seated on the elevated border part 23. The

intake extension .'21 lies wholly beneath border seat S23t and its mouth end extends through skirt 8. in4 annular recess 24 may also be 'formedbetween border .scat 23. axl hollow ring 14 to serve as an additional drip receiving lianiber outside [ofthe gas rin In Fie. 3 a series of air nino's 4f are shown in the drip pan ad acent each boss 115 and intermediate the baseiends of the gas jets, and in `Fig. 6 similar openings 4', are formed in wall-7 outside-ofsaid bosses. i

In Figs. 5 and 6, I show a combined base burner and drip -pan corresponding to that shown in the other views but having a gasdistributing. ring v14: cast` integral and raised entirely ab'ove the to i wall 7. This unit also lias a skirt 8' 'an a. central drip pan 5', but the ring is relatively smaller. than the ring in Fig. l. 'Consequently in -orderv that the ellieiency of. this smallerA bui-ner be as great as the larger one I use the saine. number of pairs of gas jets as in the other case but relate them 1n a dill'erent way to permit each co-opcrating pairA to'V function without interference with the others. 'l`li us', as shown, I mount three )air of inclined gas jets 17 on three protu 'er-- /ances 15 spaced unii'ornily'- apart on the ring, and inount an additional pair of iiiclincd jets 2.1 radiali)v of the ring on other flattened laces or protubcrances 26. The bese ends o the radial jets 25 may be located beneath the month ends oi one of the other pair of 'inclined jets and the separate .streams ot' gas and nir delivered from tliescparate pairs ot jets will not. interfere with each otheig or all'cct combustion and separate burning' of the gas sti'canis directed into conlliwiicc from the opposed inoutlis ot the jets. 'l`he advantages of the present invention will be understood b v reference to the {el} lowing: 'laiik heaters, sometimes referred to as coil heaters. :fide :irni heaters or instantaneous healers` are used to heat water passing through their coils into a range boiler or tanli. 'The complete combination. when connected together so that the/water will circulate vfrom the heater to the taiilc. is called a tank heater. are niadc with single, double and triple cnil-S iii vaiions sizes'and the shells or easing-s of tbe beaters range in diameter from about' six inches to twelve inclies or more` d epcding upon the capacity of the tank. Similar Such tank heaters lio ,I tank heaters also form e. part of e large BEST AVAILABLE COPY percentage of scelled automatic storege mede with s'baseiiange or skirt, end in Bunsen mixer, within this seperate pan.

The pan is `used to collect condensation, but f independently or apart from theburner. ,v 1 In some heaters the gas is fed tothe burner from the side of the heater und some 'from 'the bottom, and the burners usually 'have mixers which extend e. distance ol'- ,Sf to 6 fromtheface orend of the'mixer tothe parl; of the burner which is provided With the gas orifices, and the gas and eil' are assumed to be properly mixed in passing through this length of mixer. In the pres# ont improvement the mixer is `elim'ine'ted which reduces `the weight, and Athe present 'improvement also does sway with a heavy.

burner made of several parte and e seperate pan to collectcondensation'. A s'construeted, the present burner permits introductionot air for combustion through the center or in tcgral part of the burnerand situated con! i other` places of advantage iut-he burner itself, andalsopromotes quicker evenmintionv o't vc(indentation -asthe penis an 1ntiguous to and near theieme. ln thetconnection it should' be understood that such condensation hes a powerfuldestructive etfeet on iron and that it is especially desirisV vable that the collected liquid. be' ewipe` rated rapidly and carried away with ,the llames'. By melting the pen' en integral part of the burner the Weight and height of the heater 'may be reducedat its lower end, end such a'hurner unit permits quicker assembly and attachment. It 1sv also less f bulky and requires s smaller ship ing crete,

and there is less shipping bre nge,` and where replacements are to bemede the re?- pacement rcosts and labor are greatly re' i duced. The compactconstruction of the unit else erxnits 1t to be cast of aluminum' A. A c

p comprisinga circular ,Qns-distributing'body.

without prohibitive'cost,thus reducing the weightto a minimum, und' there is the added advantage-that aluminum vwill not be :1f-

fected detrimentally by the drippege The nn'itshown vin and 7 contains all the advanteges'enuinerated and` in addition the speciali arrangement o1' jets concentrates e .large'volume of heet inizi `smell `aren-and 1 vpermits the -malino or' u smaller-.burner than the `n-tlfier Without oss in eiiiciency. In both units', theV )et construction fend design and the arrangement of the jets in pairs, is im'- portant in applyingfind directing the thunev to'the-coils;` in a proper wey to develop high heating efliciency, lend the 'compact ari-enge nient of all the arts in a single unit with the jets'mountedP as shown contributes stili further to that desirable result.
